Get authorized external page with web.xml

[tcplomp]

There is a public API that I want to use on a Mindtouch page, however when using this code:
{{ web.xml{source: "http://webservices.ns.nl/ns-api-avt?station=ut", ttl: "60"} }}
I get an error 401.
Normally I would add the username/password in the url (http://username:password@webservices.ns.nl), but unfortunatly the username is my email address, and the '@' sign in the email address is mallforming this URI.
Does anybody have an idea how I would target this (apart from creating specific application, that functions as a proxy)?

Thanks,

Ton

This page says try to replace the @ with %40, here they managed to make it work by replacing it with the + symbol.
